These are great glasses for late afternoon into evening rides when you want to start with sunglasses but finish with clear glasses. The fogging only happens in late fall when the evenings get cool. No fogging issues in the summer.

These have the same comfortable, lightweight frame as the old Nashbar glasses that had light yellow lenses. I prefer the older, non darkening lenses because they gave adequate protection in most conditions and still offered good visibility in dark places like tunnels, etc. The photochromatic lenses are better than plain dark lenses but still don't lighten fast enough when entering heavy shadows or a tunnel. They are a little too dark for overcast or light rain.

Used for road cycling & mountain biking both. Positives: Just enough tint to cut the glare without diminishing perception of visual detail; good fit for a large head (size 7 5/8). Negative: they scratch easily. Still, good value for the price.

I have owned these glasses for almost 2 years, use them about 2x/week for mountain biking and they are still working great. They fit well and are lightweight. I find they stay on well and don't slide down my nose even when sweating. They are especially great for rides at sunset where I get sun protection and they light up to almost clear for riding at night. I use them day and night. I like that the lens doesn't get too dark in the sunlight as I prefer a lens that is not too dark so I can see the terrain best.

As for some who say they fog, all glasses fog, especially in cold weather, and you simply need a little anti fog spray to prevent fogging. In a pinch, use your spit. (A scuba diving staple to keep your mask from fogging.)

I recommended these to two friends who also bought them and they love them too.
